Question about GoPro El Grande

I can answer your question as follows: Yes, you can also use this extension pole in salt water. That's exactly why I bought it, because as I saw on someone else's website, I also want to use it with the GoPro Hero 7 for whale watching.

I'm not sure. To be honest, I wouldn't try it either. I used another rod and it was really damaged by the salt. Regular rinsing with fresh water did not help either.
